A range of pneumatic timers with ranges 0.5 - 180 seconds. They are designed for permanent setting within control cabinet environments and do not show time elapsed/set.
This timer is based on a 3/2 valve and can be ordered in a normally closed (N/C) version. Reset is achieved by interrupting the control air to port 12 for 300ms and the timer is then automatically reset to its preset value.
Normally open (N/O) version available on request.
